ProxMenux/scripts/share/samba_client.sh
T
MacRimi 085cbf7e68 scope the change journal to host changes, in three sections 
The change journal exists so a sysadmin sees what ProxMenux changed on the host — its own configuration, packages and services — not how it uses the host or configures a guest. Several scripts recorded operations that are neither: disk passthrough to a VM, container conversions, VM import/export, mounting a share into an LXC. Those are restored to their original, uninstrumented form. Scripts that operate on the host while also installing a package now record only the package: format-disk keeps its exFAT-tools install, the UUP ISO builder its build dependencies, and the share/host scripts their packages, services and /etc/fstab writes, while the mount and unmount operations they used to log are dropped.

The page now reads in three sections: what ProxMenux optimized after install (each function under its menu name), what its other host scripts changed (by script), and what it installed (packages and utilities, each referencing the script that installed it). A file reads as created or modified with its diff, a service shows its state transition, and the undo line appears only when a revert is possible.

# ProxMenux - Samba / CIFS Client Manager for LXC
# ==========================================================
# Author : MacRimi
# Copyright : (c) 2024 MacRimi
# License : GPL-3.0
# https://github.com/MacRimi/ProxMenux/blob/main/LICENSE
# Version : 1.0
# ==========================================================
# Description:
# Manages Samba / CIFS client mounts from inside a Proxmox LXC
# container. Requires a privileged container (mount.cifs needs
# capabilities that unprivileged CTs do not expose).
#
# Features:
# - Mount CIFS shares (temporary and permanent via /etc/fstab).
# - List current CIFS mounts inside the CT.
# - Unmount and remove shares cleanly.
# - Auto-discover Samba servers on the local network.
# - Credentials stored in /etc/samba/credentials (root:0600).
